    Study the following tables :
    I. Dehydration Condensation Decarboxylation
    II. Isomerisation Decarboxylarion Hydration
    III. Decarboxylation Condensation Hydration
    IV. Condensation Decarboxylation Isomerisation
    Select the correct pair of answers in which the former in the pair shows the set of reactions taking place during Krebs cycle and the latter in the pair shows the set of reactions that do not takes place during glycolysis:

    A)  I and III                               

    B)  I and II

    C)  II and III                              

    D)  II and IV

    Correct Answer: A

    Solution :

                     Dehydration, condensation, decarboxylation and hydration take place during Krebs cycle. Decarboxylarion does not take place in glycolysis. Dehydration (i.e., removal of water molecule) takes place during conversion of citrate into cis aconitate in Krebs cycle. - During conversion of isocitrate ot a keto gluterate and a-ketogluterate to succinyl CoA-oxidative de carboxylation takes place. - Condensation takes place during conversion of oxaloacetate to citrate (I step of Krebs cycle). Isomerization takes place in the compounds of glycolysis.
